Not Happy

I paid for this CDL Manual; Then when received it; it’s outdated; it’s a 2015 manual ; it is now 2018 and a few months it’s going to be 2019
I want my manual to be the currant year, I won’t be buying anything from this site ever again.

Me and my wife are going for our CDL class A and just reading the DMV book just wasn't cutting it. So i found this app and it helped a lot. Keeps track of all your score. I started out low and now im scoring in the high 90% on pre test with over 400 questions. I feel more confident taking the written test at DMV
